Herewith appended below is an email I sent today to Professor Iain Stewart (and copied to all those named in it).

Dear Professor Stewart,

I wanted to express my appreciation for the sensitive way in which you handled the issues in last night’s Horizon programme and for all the facts, figures and research findings it contained. I was particularly interested in the evidence that shale gas has escaped from poorly-constructed wells in the USA. Even if the UK can improve on the 6 to 7% failure rate in the USA, 100% success (i.e. no failures) is highly improbable. Therefore, if fracking must be pursued (for whatever reason), this would make it imperative that the BGS establish baseline monitoring for methane as soon as possible. Would it be possible to get a copy of the transcript of the programme (or a list of References)?

Given my geological background and my MA in Environmental Politics, I have written a great deal about Fracking and Carbon Capture and Storage (CCS) on my blog. However, having started out very much opposed to both Fracking and CCS, my position has evolved as a consequence of ‘exchanges of views’ I had last year with Professor Peter Styles (Keele) and with Professor Robert Mair (Cambridge/Royal Society). As a result of these exchanges – summarised or linked to here on my blog – I would agree with Peter that we probably need shale gas. However, I believe Peter also agrees with me that we probably cannot afford it*. I also understand that the remit of the Royal Society specifically excluded the long-term sustainability implications of pursuing fracking.

Nevertheless, this leaves me wondering whether you could encourage the BBC to do a second programme to address the consequences of humans burning all the Earth’s fossil fuels simply because they are there; and/or the need for ‘Western’ per capita energy consumption to be drastically reduced? Having read David MacKay’s book, Sustainable Energy: Without The Hot Air, I think our biggest problem is that most people do not think holistically about the problems we face or, even worse, they seem to think concepts such as ‘ecological carrying capacity’ are just eco-Marxist propaganda. However, although it would seem that CCS is now going to be essential in order to minimise anthropogenic climate disruption (ACD), I think it is also the biggest obstacle to getting politicians to take decisive action to decarbonise our power generation systems.

Even if such a second Horizon programme is not likely, I remain very appreciative of all you have done – and are doing – to raise the profile of ACD as an Earth Science issue that should be of concern to all.
